Note 1: Absolute Maximum Ratings are those values beyond which the
life of the device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage
and how many amplifiers are shorted.
Note 3: The LT1490C/LT1491C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1490C/LT1491C are designed,
characterized and expected to meet specified performance from – 40°C
to 85°C but are not tested or QA sampled at these temperatures.
The LT1490I/LT1491I are guaranteed to meet specified performance from
– 40°C to 85°C.
Note 4: V_S = 5V limits are guaranteed by correlation to V_S = 3V and
V_S = ±15V tests.
Note 5: V_S = 3V limits are guaranteed by correlation to V_S = 5V and
V_S = ±15V tests.
Note 6: Guaranteed by correlation to slew rate at V_S = ±15V and GBW
at V_S = 3V and V_S = ±15V tests.
Note 7: This parameter is not 100% tested.
